Fiat 500: When to inspect?

Hello, after I have already tried the search without success, I ask my question now here, and hope to get a suitable answer. My Fiat 500 is in my possession in the meantime a year. The vehicle was bought as a day registration, first registration was January 2010. Now after a year there are almost 7000km on the tacho. When does the little one now have to be inspected? I mean to have heard somewhere from an annual inspection, but in the manual are always only in tervalle of 30000km. Does any of you know when I should be inspected and what costs are there? Thank you very much. Greetings, Felix.
